I have considered the option of having a UPS to keep the Genius alive when the power fails but decided against it because of the cost and the fact that all UPSs seem to be targeted at keeping desktops alive. The power conditioning benefits simply are not needed.

However being Wellington-resident I lost power for just over 12 hours this weekend.

Looking at the Genius power pack the output is 12 volts DC, implying I could use a car battery to keep it going. We have an internal garage so if I could find a way of connecting the unit to the cigarette lighter I could simply move it to the car and get it up and running. The biggest physical hurdle is finding a plug that will go into the power socket on the Genius - that shouldn't be too hard.

The nagging doubt I have is that with a VOIP unit such as this there should be options to power it from other than a mains power pack. Is there a commercial accessory available for this?

UPS's dont really care whats plugged into them - so your comment about being aimed at desktops is void. Obviously you dont try running a vacuum cleaner off one :D Cost wise, can pickup Dynamix ones for under $100 which work fine - keeps my work desktop, LED screen and network switch running for over an hour.

Plugging a router of any sort into a "desktop" UPS solution will be fine and keep the device powered up for quite some time, probably a lot more than a desktop ;)

Obviously power being out for 12hrs, a UPS might not be able to assist with... if youre that desperate to have lines up that long, buy a generator.
